Steps to reproduce:
1) Create 60 blank roles
2) Create a site template with 14 pages and about 70 portlets overall
3) Create a new site with this template

Observed behavior: It took ~20 seconds to create a new site on SSD and about ~30-50 on external HDD.

Root cause:
During portlet export permission exporter adds a record for every role in portletDataContext, even if they don't have any actionKeys, and it causes a lot of unnecessary processing at the import.

Solution:
Skip roles which doesn't have actionKeys during permission export.
